I'd start a charity for them! And I'll even donate to them like a million times a day! And as a famous person, i can afford commercials, so i will make some encouraging people to donate :) (Oh, and I'll build some low-cost apartments/houses so the homeless people will have somewhere to stay)
i would help them by planting plants that they can eat and 4 the hobo's or home less i would give them all a hug then feed them all then give them each 500 $$$ then say go on with your life
